STRINGSTRING
SNU66 protein (Saccharomyces cerevisiae) - STRING interaction network
"SNU66" - Component of the U4/U6.U5 snRNP complex involved in pre-mRNA splicing via spliceosome in Saccharomyces cerevisiae
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

SNU66Component of the U4/U6.U5 snRNP complex involved in pre-mRNA splicing via spliceosome; also required for pre-5S rRNA processing and may act in concert with Rnh70p; has homology to human SART-1; Component of the U4/U6.U5 tri-snRNP particle, one of the building blocks of the spliceosome. Required for pre-mRNA splicing (587 aa)    
Predicted Functional Partners:
HUB1
Ubiquitin-like protein modifier; promotes alternative splicing of SRC1 pre-mRNA; binds non-covalently to the HIND domain of Snu66, may function in modification of Sph1p and Hbt1p, functionally complemented by the human or S. pombe ortholog; mechanis /.../ub1p adduct formation not yet clear; Forms conjugate with SPH1 and HBT1. Involved in morphogenesis (73 aa)

  0.999
PRP31
Splicing factor, component of the U4/U6-U5 snRNP complex; Promotes the association of the U4/U6.U5 tri-snRNP particle with pre-spliceosomes to form the mature spliceosomal complex (494 aa)

PRP8
Component of the U4/U6-U5 snRNP complex, involved in the second catalytic step of splicing; mutations of human Prp8 cause retinitis pigmentosa; Functions as a scaffold that mediates the ordered assembly of spliceosomal proteins and snRNAs. Required for association of BRR2 with the spliceosomal U5 snRNP, and the subsequent assembly of the U4/U6-U5 tri-snRNP complex. Functions as scaffold that positions spliceosomal U2, U5 and U6 snRNAs at splice sites on pre-mRNA substrates, so that splicing can occur. Interacts with both the 5’ and the 3’ splice site, as well as the branch region. Has [...] (2413 aa)

BRR2
RNA-dependent ATPase RNA helicase (DEIH box); required for disruption of U4/U6 base-pairing in native snRNPs to activate the spliceosome for catalysis; homologous to human U5-200kD; RNA helicase that plays an essential role in pre-mRNA splicing as component of the U5 snRNP and U4/U6-U5 tri-snRNP complexes. Involved in spliceosome assembly, activation and disassembly. Mediates changes in the dynamic network of RNA-RNA interactions in the spliceosome. Catalyzes the ATP-dependent unwinding of U4/U6 RNA duplices, an essential step in the assembly of a catalytically active spliceosome (2163 aa)
